Masu matsayin masurautar kammaloli (DRM) a cikin faduwar hanyoyi na gajarta

Wannan yanayi yana nuna girman da kuma hali na jerin cin-cinin tsakiyar fagen da ke cikin SF6 circuit breakers. Yanayin DRM (Dynamic Resistance Measurement) ana yi ne tare da rarrabbin karamin DC current a kan cin-cinin gajerar da ta ce ta hanyar wannan circuit breaker a lokacin da ya shiga aiki. Sule, abubuwan da ake sauka masu yanayi suna ci gaba suka kula da kuma baka resistance a kan wata lokaci. Idan yadda cin-cinin yake zama ba a tabbatar, za a iya samun resistance a kan har yanzu daga cikin cin-cinin. Tare da yanayin DRM, za a iya faɗinsu girman da ke cikin arcing contact. An kowane hanyar da ke so kuɗi waɗanda za a iya yi shine zuwa tafakudancin circuit breaker.

A cikin SF6 circuit breakers, arcing contact yana cikin tungsten/copper alloy. Daga kowane lokacin da ita ke tattara, yana ƙasa da kuma zama ƙarin. Circuit breaker yana lalace da arcing contact wear a lokacin da ita ke yi aiki na musamman, kuma a lokacin da ita ke tattara short-circuit currents. Idan arcing contact yana ƙarin da ya fi shi ko a hali mai ƙarfi, cin-cinin gajerar da ke cikin main contact surfaces zai iya ƙara da arcing. Wannan zai haifar da resistance, kisan hoton da kuma, a wuraren mutane, yanayin kwalliya. Kamar yadda ake bayyana a cikin tasweer, main contact resistance an samun shi a kan lokacin da ake yi open ko close operation a DRM.
